Abstract

PCT No. PCT/GB89/01272 Sec. 371 Date Jun. 21, 1991 Sec. 102(e) Date Jun. 21, 1991 PCT Filed Oct. 25, 1989 PCT Pub. No. WO90/04446 PCT Pub. Date May 3, 1990.A rotary screening device for separating unwanted solid matter such as sewage, weeds, tar globules and fish from water which is to be used for special purposes such as water cooling or other plant processes. The device comprises a rotating hollow stack of closely spaced coaxially mounted annular discs, each of which is provided with peripheral teeth upon which unwanted solid matter may be caught and carried away to a collection zone and by scraper elements engaging annular tracking surfaces between the teeth on adjacent discs. The tracking surfaces have apertures or slits to permit passage of cleaned water to the interior of the hollow stack to which may be connected stationary ducting means for conveying the cleaned water therefrom.
